MAGNETIC RESONANCE IMAGING APPARATUS |
| 摘要 |
An MRI system according to an embodiment includes an MRI sequence controller and an MRI system controller. Serving as a prescan unit, the MRI sequence controller performs a prescan for acquiring a sensitivity distribution of a coil. Serving as a main scan unit, the MRI sequence controller performs a main scan for acquiring signals of a magnetic resonance image. Serving as a corrector, the MRI system controller corrects the sensitivity distribution in accordance with a distortion that is contained in the magnetic resonance image and that results from the performing of the main scan. Serving as a generator, the MRI system controller generates an output magnetic resonance image using the corrected sensitivity distribution. |
